Culm-nodes bearded. Lateral branches ample. Leaf-sheaths 3-7 cm long; mostly shorter than adjacent culm internode; hirsute; with tubercle-based hairs; outer margin hairy. Ligule a ciliate membrane; 1.5-2.5 mm long. Collar pubescent. Leaf-blade base broadly rounded. Leaf-blades linear, or lanceolate; 7-25 cm long; 5-7 mm wide. Leaf-blade midrib evident. Leaf-blade surface hirsute; densely hairy; hairy on both sides. Leaf-blade margins scabrous; ciliate. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle; terminal and axillary. Axillary inflorescences intermingled with terminal. Panicle open; oblong; effuse; 5-15 cm long. Primary panicle branches spreading; branching divaricately. Panicle axis scabrous. Panicle branches stiff; scabrous; pubescent in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 2.6-2.8 mm long; 1-1.2 mm wide; falling entire. Floret callus evident; 0.2-0.5 mm long.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 2.6-2.8 mm long; 1-1.2 mm wide; falling entire. Floret callus evident; 0.2-0.5 mm long.
    Glume
    Glumes reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 1.8-2.2 mm long; 0.5-0.75 length of spikelet; membranous; without keels; 5-9 -veined. Lower glume primary vein scabrous. Lower glume apex acuminate. Upper glume ovate; 1 length of spikelet; membranous; without keels; 7-9 -veined. Upper glume apex acuminate.
    Florets
    Basal sterile florets barren; with palea, or without significant palea. Lemma of lower sterile floret similar to upper glume; ovate; 1 length of spikelet; membranous; 7-9 -veined; glabrous, or pubescent; acuminate. Fertile lemma elliptic; dorsally compressed; 1.8-2 mm long; indurate; pallid; without keel; 7 -veined. Lemma surface glabrous, or pubescent. Lemma margins involute. Palea involute; indurate.
